摘要
The present invention discloses a bidirectional transmission network apparatus based on a tunable rare-earth-doped fiber laser source. It is useful in wavelength-division-multiplexing access networks. The fiber ring laser not only generates downstream data traffic but also serves as the wavelength-selecting injection light source for the Fabry-Pérot lasers (or vertical cavity surface emitting lasers) located at the subscriber site. The fiber laser is constructed based on optical filtering, polarization control and noise suppression techniques.
